BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus caryophyllus L., grown commercially as a container plant and hereinafter referred to by the name ‘Hiltasha’.

The new Carnation plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new container Carnation plants with numerous attractive flowers.

The new Carnation plant originated from a cross-pollination made by the Inventor in De Kwakel, The Netherlands in May, 2013 of a proprietary selection of Dianthus caryophyllus L. identified as code number 2242, not patented, as the female, or seed, parent with a proprietary selection of Dianthus caryophyllus L. identified as code number D 1152, not patented, as the male, or pollen, parent. The new Carnation plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in June, 2014.

Asexual reproduction of the new Carnation plant by terminal cuttings propagated in a controlled greenhouse environment in De Kwakel, The Netherlands since March, 2015 has shown that the unique features of this new Carnation plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Carnation have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hiltasha’. These characteristics in combination distinguish ‘Hiltasha’ as a new and distinct Carnation plant:

-   -   1. Compact, upright to broadly spreading and uniformly mounding         plant habit.     -   2. Freely branching habit.     -   3. Early and freely flowering habit.     -   4. Purple-colored double flowers.     -   5. Good container and garden performance.

Plants of the new Carnation differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Leaves of plants of the new Carnation are broader and are         darker green in color than leaves of plants of the female parent         selection.     -   2. Plants of the new Carnation are more freely-flowering than         plants of the female parent selection.

Plants of the new Carnation differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Carnation have green-colored leaves whereas         plants of the male parent selection have greyed green-colored         leaves.     -   2. Plants of the new Carnation are more freely-branching than         plants of the male parent selection.     -   3. Plants of the new Carnation flower earlier than plants of the         male parent selection.

Plants of the new Carnation also can be compared to plants of Dianthus superbus ‘Holkahori’, not patented. In side-by-side comparisons, plants of the new Carnation differ primarily from plants of ‘Holkahori’ in the following characteristics:

-   -   1. Leaves of plants of the new Carnation are broader than leaves         of plants of ‘Holkahori’.     -   2. Flowers of plants of the new Carnation are flatter than and         not as cupped as flowers of plants of ‘Holkahori’.     -   3. Flowers of plants of the new Carnation are purple in color         whereas flowers of plants of ‘Holkahori’ are red purple in         color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Carnation plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Carnation plant. The photograph (FIG. 1) comprises a side perspective view of a typical flowering plant of ‘Hikasha’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the late winter and early spring in 10.5-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial container Carnation production. During the production of the plants, day temperatures ranged from 16° C. to 20° C. and night temperatures ranged from 16° C. to 18° C. Plants used for the photograph and description were three months from planting and were pinched one time about one week after planting rooted young plants. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
